Relaxation Effects in the Ferromagnetic Resonance

Abstract

The spin-lattice relaxation time, $T_1$, has been determined in single crystals of nickel ferrite, by using the ferromagnetic resonance effect at a frequency of 9000 Mc/sec. At high levels of microwave power, the saturation effect is observed both in the resonance absorption and in the component of magnetization along the static field. $T_1$ is computed from these data.
